Spring Boot properties in 'application.yml' not loading from JUnit Test

Question

What am I doing wrong? I\'m using this little standalone App which runs and finds my src/main/resources/config/application.yml. The same configuration doesn\'t work

Answer 1

In my case I was trying to test a library without a @SpringBootApp declared in the regular app classpath, but I do have one in my test context. After debugging my way through the Spring Boot initialization process, I discovered that Spring Boot's YamlPropertySourceLoader (as of 1.5.2.RELEASE) will not load YAML properties unless org.yaml.snakeyaml.Yaml is on the classpath. The solution for me was to add snakeyaml as a test dependency in my POM:

    
        org.yaml
        snakeyaml
        1.19
        test
